There are 4 bodies but only 2 heads in this 19th Century Japanese woodblock of pregnant women.

The woodblock print “Mimochi on’na natsu no tawamure – Gotō juttai no zu” (Pregnant women playing in summer heat – 5 heads with 10 bodies at the complete image) was made by artist Kunitoshi Utagawa in 1881.

As a illusions reader, you’ve undoubtedly already seen your share of Penrose Triangles both here and elsewhere. Even so, the concept remains fascinating, particularly when turned into real-life objects, because the design itself is, in actuality, impossible.

That’s why this Steelwork Illusion created by Deskarati is simply so fascinating -the illusion is so subtle and the photo looks so real that your mind wants to accept that it is an unaltered photograph. That is, until your brain starts to follow the lines of the steel framework and you begin realizing more and more just how impossible this building design really is.

Tthis Hollywood movie starring James Franco, called “127 Hours“ goes about a mountain climber who becomes trapped under a boulder while canyoneering alone somewhere in Utah. In order to survive, he then resorts to desperate measures. There was this subtle optical illusion on the cover, one you could easily overlook if you don’t pay close attention. Let me share the original poster (lacking promotional text and labels) which helps the illusion stand out more. Can you see it?

Here’s an incredible optical illusion. You’ll need to wait few seconds before the .gif file fully loads, but when it does I promise you’ll love it! Once the animation has started, you’ll quickly notice how outer-rim dots begin shifting themselves up and down. But what is so cool here, is that this is actually an illusion! Our little dots haven’t changed their starting position one bit! The only thing changing here is their color; from white to black and vice-versa!

Mr. Hou didn’t expect to become an internet sensation after he uploaded some photos of his 3D chalk art pieces onto a Chinese forum a few weeks ago. After all, he’s just an average Chinese citizen who enjoys drawing for his little boy. Now, people from all over the web are referring to him by a new nickname – “Chalk God.”

“I think these 3D artworks actually aren’t that rare/surprising, but the idea is very key, and only with the idea can you move people,” says Mr. Hou. “For example, I once went to a tourist sight/attraction, and there was a sculpture at this intersection. Below the sculpture, on all four sides, were a bunch of advertisements for counterfeit official documents. I felt this was so representative of China today, so I started drawing, never expecting to become so popular.”

Peter Tse , from Dartmouth College (USA) has get anether nice view for the classic afterimage optical illusion. If you haven’t encountered afterimage illusions before, I strongly recommend visiting Ilusiones opticas. So why is this illusion different? By using it, you can reveal if your brain predominantly sees horizontal or vertical lines! To begin, you’ll need to fixate the colored image (one on your left) by looking at the fixation spot for about 60 seconds. Now shift your eyes to the fixation spot surrounded by rectangular outlines. Which afterimage did you see first? You can manually shift which afterimage you experience by attending to one rectangle and then the other. If you attend to the vertical outline rectangle you will see the afterimage corresponding to it, and if you attend to the horizontal outline rectangle you will see the different afterimage corresponding to it. Now wasn’t this great?!

To see the genius of Belgian artist Fred Eerdekens, the lighting is very important, as demostrated too Francis Tabary . That’s because Eerdekens’ work relies on the shadows cast by sculptures — which are made of bent wires in this example — to unveil the hidden message to the viewer. Can you read all of the Eerdekens messages? What do they say?
